====================================
Technical Details
For the photo shown above, here are the key metrics:
Focal Length: 70.0 mm - this is very long length, the longest in my current lens.
Flash: Not Used - it is completely useless for flash to capture night scene.
Aperture: f/25.0 - very small indeed. This is to ensure the sharp image of the picture. The small it is, the sharper the image is.
Exposure bias: -0.67 - this is very key. Since the auto-exposure meter will take the dark sky into consideration, it makes sense to under-exposure a little bit so the color of the building reveals.
Exposure: Program - this is the [P] mode on the D50 camera.
Exposure time: 8.000s - this is maybe the most important thing. I used exposure time of 8 second. That is after you press the shuttle button, count 1, 2, 3, 4, 5, 6, 7, 8. I know, that is very long. This makes it possible for me to use smaller Aperture to get the sharp image.
The Key Challenge - to Hold the Camera Tight
1/60 second is the threshold for most people to hold the camera tight enough. The key challenge for me to take night scenes is to hold the camera tightly as possible, for as long as 8 seconds!
I don't want to bring a tripod with me. That is huge, and again, I don't want to be a professional photographer. Even if I do, I don't want the burden of a tripod ruin my pleasant travel mood.
I always find something, like the pole near the river, or a bench, or even a solid grand. Then put the camera directly onto the solid supporting surface. Then set the exposure to long enough, so even there are some initial small movement of the camera, it won't impact the imagine too much.
